When you attempt to power on, can you hear the fans spin at all?

Did you touch any of the internal components, potentially causing static shock?

Hmmmm, odd. I'm not entirely sure what else can be done at this point. =/ Hopefully someone else may be able to help you here. Right now, I'm thinking it could be the monitor lead or the motherboard.
